FOLDING WOVEN-WIRE MATTRESS.

SPECIFICATION forming part of Letters Patent No. 357,558,dated February 8, 1887.

Application filed May 24, 1886. Serial No. 203,075. (No model.)

To all whom it may concern:

Be it known that we, FEED KUNKEL and MARrNUs VAN SAS, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Folding Woven-Wire Mattresses; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to woven-wire mattresses, and has for its object to improve this 'class of devices, whereby they may be folded up when not in use, to occupy less room, and at the same time to render them more convenient for handling, storage, and transportation. These objects we attain by the construction, substantially as hereinafter described with reference to the accompanying drawings, in which Figure 1 represents a perspective view of our invention in its opened position; Fig. 2, a transverse section of the same; Fig. 3, a detail, and Fig. 4 a perspective, of our mattress folded up.

Referring by letter to the drawings, A A

represent two woven wire-mattress sections hinged together. These mattress-sections are each composed of a single sheet of the wellknown woven-wire material of suitable width, secured at its ends between two transverse bars, B G, the outer bars, B, of both sections being joined by hinges D. The inner bars, 0, of one section are each provided with a bolt, E, that engages a keeper, F, on the adjacent inner bars of the other section, to retain the mattress in its open position. The wovenwire material of each mattress-section is made taut, and thus given suflicient spring by means of beams G, to the ends of which are bolted angle-irons H H, that terminate in trunnions a, designed to bear against the under sides of the end bars, 0, and be there retained by means of bearing-plates'I, bolted to these bars, the bolts 7) being passed through and their heads rested on stay-plates K upon the upper sides of said bars, to prevent the latter from being split by the strain brought thereon.

When the mattress is not designed for use, the beams G are turned in, the boltsE drawn, and the sections folded up in a compact form, as illustrated by Fig. 4, thus permitting said mattresses to be easily handled and at the same time effecting a saving in space when the same are stored or shipped in lots.

The mattress being opened out, the end bars B are designed to rest upon the usual cleats on the head and foot boards of a bed, the brace-beams G being vertically depended, as shown by Fig. 2.

In case it is not convenient to employ the mattress upon a bedstead, the brace-beams G may rest upon a floor, and thus give ample support to said mattress without in any way interfering with its utility, while at the same time a suflicient elevation, is had for the occupant above the fioor away from drafts. To prevent longitudinal play of the brace-beams G,

the trunnion ends a of the angle'irons H H are provided with collars d, that bear against the end bars 0.

By the construction above described we provide a simple folding wire mattress that is capable of being manufactured without increase of cost over the ordinary non-folding mattress of this description, and that is also very durable, not likelyto get out of order, and possessed of many decided advantages.

We are aware that a bed-frame formed of sections hinged together and provided with brackets having lugs or stops, and curved braces fitted to said brackets and abutting against said lugs, is not new, and such we do not claim.

Having thus-fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A woven-wire mattress consisting of two hinge-joined sections, each provided with a trnnnioned brace-beam, said beams when opened out being parallel with the plane of the wire material on the sections, to form a support for the mattress independent of a bedstead, and a locking mechanism to retain said mattress in its open position, as set forth.

2. A woven-wire mattress consisting of two hinge-joined sections having bearing-plates secured to the under sides of their end bars, and brace-beams having bolted to their ends angle-irons that terminate in trunnions and fit between said plates and bars, said trunnioned ends of the angle-irons being provided with stationary collars, as set forth.

3. A woven-wire mattress comprising two In testimony that we claim the foregoing we hingejoined sections, each consisting of a have hereunto set ourhands, at Milwaukee, in single sheet or" wire material secured to transthe county of Milwaukee and State of Wisverse bars each of the inner bars being proeonsin, in the presence of two Witnesses.

5 vided upon its under side with a bearing-plate and upon its top with a stay-plate, and a SAS brace-beam having its extremities secured to angle-irons that terminate in trunnions to fit \Vitnesses: between said bearing-plates and their respect H. G. UNDERWOOD,

1o ire end bars, as set forth. MAURICE F. FREAK.
